Α-Arylation Of Cyclopentanone : Palladium-Catalyzed Coupling Of Enamines And Aryliodides & N-Acyloxazines As Novel Bicyclic Weinreb Amides, Kristina M. Gehring
Α-Arylation Of Cyclopentanone : Palladium-Catalyzed Coupling Of Enamines And Aryliodides & N-Acyloxazines As Novel Bicyclic Weinreb Amides, Kristina M. Gehring
Honors Theses
The introduction of an aryl group a to a carbonyl is a useful step in the preparation of a variety of biologically interesting compounds. The palladium-catalyzed a-arylation of ketones and esters, through their enolates, has received a great deal of attention lately. Despite these efforts, cyclopentanones remain one of the most difficult classes ofketones to arylate. Many of these methods suffer from the limitation of the relatively basic reaction conditions needed in order to prepare the enolate nucleopbiles insitu. The direct palladium-catalyzed α-arylation of enamines as an alternative route to αaryl ketones bas received very little attention and might be …
Synthesis And Characterization Of Novel 1-Substituted Meta-Terphenyls For Platinum Complexes, Sarah Marie Sparks
Synthesis And Characterization Of Novel 1-Substituted Meta-Terphenyls For Platinum Complexes, Sarah Marie Sparks
Honors Theses
The unique luminescent properties of aryl, tridentate platinum complexes has led to an increased interest and investigation of various binding modes, with an emphasis on ligand design. These complexes are anticipaterl to be useful in chemical sensing, organic light emitting diodes, and solar energy converters.
Efficient Synthesis Of N9-Alkylguanines : & Evaluation Of A More Highly Conjugated Analog Of Guanidinium-Rich Molecular Transporters Using A Ph Dependent Fluorescence Assay, David E. Olson
Honors Theses
Synthesis of N9-(2-chloroethyl)guanine from 2-amino-6-chloropurine was accomplished in three steps with an overall yield of 83%. All products were purified via crystalli7.ation and no chromatography was required. Selective crystallization of the desired N9 isomer subsequent to the key alkylation step completely and efficiently removed the N7 isomer. This compound was shown to be a versatile reagent in the synthesis of various N9-substituted guanines.
The Synthesis And Characterization Of A Metal Complex Containing Chemically Non-Equivalent Axial Cyanide Ligands, Derek D. Wayman
The Synthesis And Characterization Of A Metal Complex Containing Chemically Non-Equivalent Axial Cyanide Ligands, Derek D. Wayman
Honors Theses
In order to analyze the magnitude and factors which effect 13C-13C NMR coupling through a metal center, we have synthesized an octahedral dicyano cobalt (III) complex in which two trans cyanides are chemically non-equivalent. Although similar complexes have been reported, their spectroscopic characterization with isotopically labeled cyanide (13CN) has yet to be studied in detail.
